To (L11 whom it may concern:

'S e 1r, \xnoNn that 1, iii nun: C. BUxxouT,

a citizen of the United States, residing at Chicago, 1n the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car-Couplers; and I (I0 hereby (lGOlElle the following to be a full, clear, and exact description of the 1n- VOlltlOll, SHCh as will enable others skilled in 1311a art, to which it a ertains to make and use the same My invention relates to the construction Of CH1 couplers 0f the vertical plane type and more especially to that class otcouplers in WlllCl] the coupler head is yield-in l attached to the car body by a plurality of draft stems that are pivotally connected t0 the coupler head.

The object of my invention is to provide 2a a simple, compact, easily operated, strong and durable coupler which is adapted to be connected to the car body by a plurality of draft stems and which may be provided with a vertically sliding gravity lock, a knuckle opener actuated by such lock and a supplemental lock, or so-called lock-to-the-lock, for preventing the accidental unlocking of the coupler when the car to which it is attached is in service.

In the construction of car couplers which are yieldingly connected to the car body by a plurality of draft stems, it is desirable that the coupler head shall be of small di- Specification 0f Lcttcl'i Intuit Application filed September 13, 1311.

that of an adjacent car, drags upon the track and is apt to be torn froin the Car.

By the construction and combination of the parts hereinafter described a coupler head of comparatively small dimensions serves to furnish a support and to cooperate with a knuckle, lock, knuckle-opener mechanism and lock-tothe-lock devices, the construction, therefore, being particularly well fitted for the type of couplers heretofore mentioned in which the coupler head is yieldingly connected to the car body by means of a plurality of draft stems.

In the drawings chosen for the purpose of illustrating the invention, the scope whereof is pointed out in the claims,

Figure 1 is a plan view of a three-stem coupler embodying my invention; Fig. 2 is a horizontal central section of the coupler head shown in Fig. 1, the knuckle and knuckle-opening device being shown in plan and the parts being shown in locked posi tion; Fig. 3 is a vertical section taken on the line 3-3, Fig. 1; Fig. 4 is a side elevation of the devices shown in Fig. 1, a portion of the coupler head and knuckle being broken away to show the knuckle-Opening device; Fig. 5 is a detail side elevation of the coupler lock, the means for engaging and actuating the knuckle-opener being omitted; Fig. 6 is a detail front elevation of the coupler lock together with the knuckleopener actuating means carried by said lock;
